To all whom zit may concern.'

Be it known that I, WILLIAM DICHMANN, a citizen of the United States,residing at Oshkosh, in the county of Winnebago and State of Wisconsin,have invented new and useful Improvements in Machines for Making Bottle-Vrappers, of which the following is a speciiication.

My invention relates to a machine for the manufacture of bottle-wrappersused in packing bottles to prevent breakage.

r1`he object of my invention is to provide a continuous method ofmaking, forming, and

crimping circular crimped bottle-wrappersand to provide a continuousmachine that will insure a maximum rapidity of manufacture.

My invention consists of certain other new and novel features ofmechanism and construction, which will be hereinafter more speciiicallyset forth and described.

In the accompanying drawings, Figures 1, 1, 1b are views arranged onsuccessive sheets showing my improved wrapper-forming machine in sideelevation. Figs. 2, 2", and 2b are similarly arranged upon successivesheets, showing a top plan view of the machine, portions of the frameabove the main frame being shown in section. Fig. 3 is a transversevertical section of the machine, taken upon the line A A of Fig. 1. Fig.4 is a similar vertical sec'- tional view on the line BB of Fig. 1. Fig.5 is a similar vertical sectional view taken upon the line C O of Fig.1l. Fig. 6 is a transverse sectional View through the strip of wrappingmaterial produced by the machine before it is formed into a completedwrapper. Fig. 7 is a vertical sectional view taken centrally through thefeed-rolls of the mechanism. Figs. 8, 9, and 10 are detail sectionalviews of the principal successive forming-rolls, showing their relationto the central stationary former. Fig. 11 is a side elevation of acompleted cover. Fig. 12 is a transverse sectional view through the samein its cylindrical form looking toward the crimped neck portion thereof.Fig. 13 is a side elevation of the cutter employed at the end of thewrapper-forming machine for cutting' the wrapping material ofi' .inproper lengths.

1 1 represent the top rails of the frame, and 2-represents one of thebottom rails.

3 3 3, &c., represent the upright standards of the frame.

4 4 4, Sac., represent the cross-rails of the frame.

5 represents the main shaft.

rlhe power is applied to the pulley 6.

The bottle-wrapper is composed of top and bottom sheets of paper 7 7 andan intermediate lilling of flexible material 8'.

9 represents the roller for the bottom paper, and 10 represents theroller for the top paper.

11 represents an inclined trough,upon which the flexible filling 8 isspread and fed to the machine on top of the endless belt 12.

13 is an inclined support for the endless belt 12.

14 is an adjustable tightener to regulate the tension of the belt 12.

The filling 8 passes from the endless belt 12 onto the lower strip ofpaper 7 over the roller 15.

16 represents the driving-roller for moving the endless belt 12.

17 is a pressure-roller to properly compress the iiexible material 8 asit passes on the endless belt 12.

18 represents bevel-gears transmitting' the power from the main shaft tothe bottom forming-roller 19, Fig. 3.

21 represents gears transmitting the power from the forming-roller 19 tothe top forming-roller 20.

22 is a sprocket that operates the endless chain 23 to drive thepressure-roller 17.

24 represents the sprocket attached to the forming-roller 17, whichoperates the endless chain 25, passing round the idler 26 and over thesprocket 27, which is attached to the roller 16, that drives the endlessbelt 12.

The lower forming-roller 19 is recessed at 28, and a correspondingprojection 29 in the top forming-roller 20 travels in said recess forthe purpose of forming in the bottom paper 7 a trough 30 to receive theflexible tilling 8, Fig. 6.

31 represents a recessed guide-trough in which the lower strip of paperpasses as it is carried along, the flexible material being dischargedupon the paper at 15.

32 represents a pressure-roller to confine the flexible material as itpasses along upon the bottom strip of paper 7.

33 33 are side boards each side of the trough to confine the flexiblematerial as it .passes along.

The top strip of paper 7 is drawn from the roller 10, round a flangeguide-roller 34 and over the glue-rollers 35 35, which operate in IOOthe glue-pan 36 and supply a continuous strip of glue against the underside of the paper at each edge.

37 is an adjustable scraper to regulate the supply of glue upon therollers 35 35.

The paper 7 is drawn round the rollers 38 38 and over the flangeguide-rollers 39 39 and between the pressure-rollers 40 41, where it ispressed against and attached to the bottom strip of paper 7, containingthe flexible material 8, as it passes along. The pressure-rollers 40 41serve also to draw the two strips of paper 7 7/ from their respectiverollers 9 and 10.

42 represents a sprocket-wheel upon the same shaft as the roller 40 andreceives the power by means of the endless chain 43, connecting with thesprocket 44 upon the same shaft as the roller 19, which is geared to themain driving-shaft .5 by the bevel-gears 18.

45 is an adjustable idler for taking up the slack of the endless chain43.

46 is a sprocket upon the same shaft as the roller 32, which is alsooperated by the endless chain 43.

For the purpose of keeping the strips 7 7, which inclosc the flexiblematerial 8, at all times tautI provide a ratchet-wheel 47, keyed to theshaft 48, which carries the recessed roller 40. The spring-actuatedpawl49, which is rigidly attached to the sprocket 42, operates on theteeth of the ratchet-wheel47. The sprocket 42 is permitted to turn uponthe hub of the ratchet 47. As the feed-rollers, which will behereinafter mentioned, operate to draw the paper through the machinethis pawl-andratchet mechanism permits the packing-tube to be drawnforward, so as at all times to be taut. I regard this as an essentialfeature of my invention, as without the operation of the pawl andratchet the action of the endless chain will not provide a propertension. In order to gain this tightness, the feed-rollers hereinaftermentioned are constructed of a diameter slightly greater than the radiusof the pressure-rollers 40 41 and have a double revolution, so that theywill operate faster in pulling the strips along, and thereby gain thenecessary tightness, which is relieved automatically by the operation ofthe pawl and ratchet, the ratchet advancing a tooth from time to timewhen the pull becomes too strong. The rollers 41 41 are idlers revolvingloosely upon the shaft 50 and are held in a lateral position by thecollars 51 51 5l 5l rigidly to the shaft 50.

In order to insure the requisite pressure to properly set the glue toadhere the two edges of the strips of paper 7 7', I providepressuresprings 52 52, which are adapted to press the boxes 53 53downwardly. The set-screws 54 54 are provided to hold and regulate thepressure of the springs. After the two strips of paper are glued andpressed together the double strip inclosing the flexible material isdrawn over the glue-roller 55, which operates in the heated-glue Vat 56.This distributes a narrow strip of glue along one edge of the unitedstrips upon the bottom.

57 is a roller of the same size, attached to the same shaft as theglue-roller and acts as a support for the united strips of paper as theypass along.

58 is a scraper to regulate the supply of glue upon the roller 55.

59 is a loosely-journaled roller for the purpose of properly carryingthe united strips downwardly against the glue-roller 55. The unitedstrips are then drawn along by the feedrollers and rolled into tubularform by means of the several sheaves hereinafter mentioned.

60 represents a cylindrical interior former suspended from thecross-cleats 6l 61, Sac., which are supported by the rails l 1.

62, 63, and 64 are exterior forming-rollers, sequentially convergent,over which the united strip of paper is drawn.

65 65 65, &c., represent spring-actuated selfadjusting' sheaves, asshown in detail Fig. 5. These sheaves operate to gradually turn theunited strips into a circular form round the interior former 60.

66 represents anarrow spring-actuated selfadj ustingsheave adapted topress downwardly upon the tubular cover against the lower sheave 65 topress the glued edge over the opposite edge and cause it to properlyadhere to form a tube, the glued edge having been previously coated bythe glue-roller 55. In the process of turning the fiat strip intotubular form the trough or recess 30, previously provided in the bottomstrip 7, is taken up. This provision of a trough or recess in the bottomstrip is necessary in order to furnish an extra width to be taken up inthe process of bending or rolling the united strips into a tubular form;otherwise the lower or outer strip would tear and the upper or innerstrip would buckle.

67 67 represent the feed-rollers, which draw the finished tube and feedit to the cut-off. As the tube passes between the rollers it is pressedinto a flat shape and carried along the guideway 68 to the revolvingcut-off wheel 69. The cut-off wheel is provided with twooppositely-loeated.shear-knives 70 70, which impinge against the cuttingedge o'f the stationary cutting-plate 71, attached to the end of theguideway 68.

72 represents bevel -gears conveying the power from the main shaft 5 tothe lower feedroller 67, which is geared to the upper feedroller by thegears 73 in order to secure a positive revolution of both rollers. Thesprings 74 74 serve to press the upper roller downwardly to provide aproper tension.

75 75 are adjusting-screws to hold and regulate the springs 74 74.

'Ihe pressure-rollers 67 67 are geared so as to revolve twice as fast asthe pressure-roller IOO 40 and are constructed of a diameter slightly inexcess of the radius of the -pressure-roller, so as to constantly pullthe strip taut, as hereinbefore described. The feed-rollers 67 67thereby always provide a draw, which is relieved automatically by theratchet-wheel 47, as hereinbefore described.

76 represents a shaft journaled to the frame 1 and operated from themain driving-shaft 5 by means of the gears 77. The shaft 76 operates thecrimping device. The crimping device consists of two cams 78 78, betweenwhich the circular bottle-cover is drawn after it is cut off by thecutting-wheel 69. The cams are operated toward each other by the gears79 79, and the motion is transmitted by means of the intermediate gears80 81. The crimping-cams are provided with both a top plate 82 and alower plate 83, which support the cover as it is being drawn through.The action of the cams 78 78 crimp the top portion of the cover84, asshown in Figs. 7 and 8.

In making wrappers with the machine herein described rolls of paper forthe outer and inner portions of the covers are mounted upon the rolls 9and 10, the former being mounted in the lower portion of the machine, sothat the web of paper drawn from it may be led to the under side of theassembled portions of the wrapper, while the other web being mountedabove the machine will form the cover or top of the completed strip. Theweb of paper taken from the roll 9 is led to forming-rolls 18 and 19.The passage of the web of paper between said rolls forms alongitudinally-extending trough or depression in the paper. The troughthus formed affords ample space for the lling placed between the upperand lower web of the paper and also provides sufficient slack forpermitting of the combined strips being turned into a cylindrical formWithout crowding or crimping the inner strip of material. The strip ofpaper thus formed is led beneath the end of chute 11, the iiexiblefilling material8 Abeing permitted at this point to fall upon the uppersurface of the lower web and iill the recess or trough formed therein.The strip with the filling material upon it then passes beneath theroller 32, which presses upon the filling material in such a manner asto press and partially pack the same in place. The lower web thencepasses to the rolls 40 and 41. UJ ust before entering these rolls theupper web 7 meets the lower web, and the two webs pass through the rolls40 and 41 together. Before the web 7 reaches the said rolls 40 and 41 itisvpassed over gluing-rolls 85, by which it receives adhesive megrialupon its edges and upon one face theref. As the-two webs pass throughthe rolls 4G) and 41 the edges thereof are pressed togethier by the saidrolls, as clearly illustrated in Figi'. 4, and since the upper web isapplied Withjits glue the adhesive material face downwardly the saidadhesive material will be brought between theedges of the strips as theyare pressedtogether and secure them against separation. The combinedwebs, with the filling material between them, form a packing-strip,which is now in readiness for bending and securing in a cylindricalform. In order to provide means for holding the strip of material in itscylindrical form, glue or adhesive material is applied thereto,andalthough it may be applied to bothv edges of the strips of the materialit isV preferably applied to one edge only. The adhesive substance orglue is placed upon the strip of material by passing it from the rolls40 and 41 over a glue-vat. Arranged above the glue-vat are rolls 55 and57, one only of which extends into the gluevat 56. Both rolls are neededto hold the packing-strip in proper position; but since it is onlydesired to apply the glue to one edge of the strip it is suliicient tohave the roller 55 extend into the adhesive material. As thepacking-strip passes over the rolls 55 and 57 the glue will be depositedby the roll 55 upon one edge of the combined strip. The packing-strip isnow in readiness for formation into a cylinder, and it is led from thegluevat to the roll 62 and is passed beneath the stationary former 60.The roller 62 is formed with a concave periphery and beginsthe'operation of curving the packing-strip longitudinally. f From thispoint the web is extended to successively converging rolls arrangedabout the former 60. Thus from the roll 62 the strip passes to the roll63, which is concaved to a greater extent, and from the roll 62 thestrip passes to the still more concaved roll 64. At this point the stripwill be pressed around the lower half of the former 60. The strip then.passes along the former to the rolls 65, which are arranged to bear uponthe sides and top of the former, and the final pressureroll 66, arrangeddirectly upon the top of the former 60, will press the glued edge of thematerial strip upon the other edge thereof, so as to hold the said stripin its cylindrical form. rlhe packing-strip is now in readiness forcutting to reduce it to proper lengths. To facilitate the cuttingoperation, the strip is preferably flattened, and for this purpose ispassed between the rolls 67, which press the cylindrical strip ofmaterial at and then feed it into the trough 68, which leads to suitablecutting mechanism. The rolls 67 not only perform the functionofflattening the packing material for thev cutting apparatus, but alsogrip the packing material with suiicient tightness to feed it throughthe machine, pulling it through the successive rolls and treatingapparatus above described. pose that the rolls 67 are positively drivenby the gearing hereinbeforedescribed which connects it with the shaft 5.The iiattened packing-strip is forced along the trough 68 and throughthe open cutter-wheel 69, where it is cut off in suitable lengths by theknives 70.

IIO

It is for this pur- ISO The movement of the knife-wheel is so timed withrespect to the feed of the packing material that the said material willonly be engaged by the successively-presented knives after the saidmaterial has been fed through the open portion of' the wheel asuitabledistance to form the right length of bottle-wrapper. As the successivewrappers are cut by knives their ends are gripped between thecrimpingcams 78. The cams .7 8 are formed with crimping' portions whichextend only a short distance around the periphery of the body portionsof the cams, as will be herein seen by reference to Fig. 2b. Themovement of' the cams is so timed with respect to the cut of thepacking' material that when the material is severed from the main stripthe outer end of the cut piece will be gripped between the projecting'crimping portions, which will contract and crimp the end of the severedwrapper for a short distance-that is, suiiicient to `[it upon the neckor tapering portion of a bottle. The remaining periphery of' the cams 78will not act upon the wrapper, but the wrapper will then be in readinessto be dropped from the machine and can be used for applying to bottlesto pack the same.
